-My invention relates to new and useful 'improvements in magnetic motors and more particularly to such a motor employing permanent and electromagnets, the electromage nets preferably-being carried by the rotor of the motor and the said rotor operating within a battery of permanent magnets.

The principal object of the invention resides in assembling the permanent magnets i se that those of N. le alternate with those of S. pole'and roviding means whereby the polarity of t e electromagnets may be changed u n operation of the rotor, the polarity o the electromagnets being alter- 1I nately chan ed from to S. pole and from S. to N. po e, so that' as they pass the permanent ma ets their polarity will be changed so at they will be attracted by the permanent ma ets.

A further o ject of the invention resides in the provision of stationary contacts which are carried by the stationary part of the motor and contacts carried by the rotor and adapted to successively engage the stationz ary` contacts, the -engagement of the contacts carried by the rotor with the stationary contacts alternately changing the polarity of the electromagnets. With the above and other objects in view, l0 which will appear as my description proceeds, my invention consists in the novel de- .tails of construction, and arrangement of arts, illustrated in the accompanying rawings and described vin the following specification, and while I have illustrated and described the referred embodiments of the invention, as t ey now appear to me, it will be understood that such changes may be made as will fall within the scope of the appended claims. the drawings:

Fig. 1 is a top plan.

Fig. 2 is a transverse vertical section.

Fig. 3 is a. fragmental top plan with parts removed and arts in section.

Fig. 4 is a ttom plan, and

Fig. 5 is a diagrammatic view of the electric circuit.

In the drawings 1 indicates the base or stationary portion of my motor having the circular cut-out portion 2 which forms a well for the reception of a rotor to be later described, said well having the bottom 3 to which is secured a bearing 4 for a purpose to be later described. Secured tothe bottom 3 are two circular rows of stationary contacts, one row being'indicated at 5 and the other row7 at 6 and as quite clearly shown in the drawings the row 6 of contacts is of leas diameter than the row of contacts 5 and the contacts 6 are spaced between the contacts 5 for a purpose which will later appear. Secured'to the underside of the base 1, beneath the recess 2, is a metallic ring 5 and the

contacts

5 and 6 are secured to the base by means of the bolts and nuts 6 which pass through the base and through the ring. Supported upon the base 1 around the cutout portion 2 are the permanent magnets 7 the magnets being arranged incircular form 10 and those of N. pole alternating with those of S. pole. f The permanent magnets are of substant-iallv C-shape to provide the vertically spaced arms the inner ends of which extend flush, or vin vvertical alignment, with the side walls of the well 2. Ametallic rin or band 8 of circular formation is receive between the arms o f the permanent magnets and is insulated therefrom by the wooden blocks 9, spacing plates 10 being received between the arms of the magnets, and engaging the upper and lower surfaces of the ring or band 8 as is quite clearly shown in the drawings. Connecting the outer ends of the permanent magnets is the metal band 11 which is supported from the base 1 by means of the brackets 12 or in any other suitable manner. A plate of wood or other similar material 13 extends over the upper surfaces of the magnets and is secured to the base 1 by means of the bolts 14 orothei suitable fastening means.

The rotor which operates in the well 2 comprises the upper plate 15, the lower plate 16 and the central shaft 17 the lower end of 95 which is reduced as shown at 18 to be received in the bearing 4 secured to the bottom 3 of the well. Secured between the

plates

15 and 16 and extending beyond the outer marginal edge thereof are the electromagnets 19. The electromagnets are of substantially C-shape to provide the vertically spaced arms the outer ends of wliich extend into close proximity to the inner ends of the permanent magnets so as to be attracted thereby in a. manner which will be later described. Each of the electromagnets has a left hand coil 20 and a right hand coil 21 one end of the left hand coil bein connected to the contact 22 and one end o the right 110 hand coil being connected to thecontact 23. The opposite ends .of the coils are grounded at24 to thev upper plate 15 of the rotor. The

contacts

22 and 23 arev secured to the lower plate 16 of the rotor by means of the strips of 'insulation 25 said strips of insulation being secured to the plate 16 by the screws or bolts 26, .said screws or bolts 26 also enter- .ingthreaded openings in the lower arms of theelectromagnets whereby the lower platev 16 is secured to said magnets.' The upper plate 15 is secured to theupper arms .of the electromagnets by means of the screws or bolts 27.

When the rotor is within the well of the base 1 the contacts 22,.carried by the elec. tromagnets, will engage the outer row of conltacts 5 secured to the base whereas the contacts 23 will engage'the inner row vof contacts 6 secured to the base. The reduced end -18 of the shaft 17 willbe. received in the bearin 4. y

Recelved upon the shaft 17, above the top plate 15 is a plate 28 which has the screws or bolts 29 passing therethrough to receive the nuts 30. These bolts and nuts act as securing means for the inner ends of the braces 31, the opposite ends of the braces being secured to the base 1 as shown. The inner ends of the braces are slotted to receive the bolts 29. It will thus be seen that the lower end of the shaft 17 is supported in the bearing 4 and that the upper end of the shaft is-supported through means of the braces 31. Binding posts are shown at 32, 33 and 34.

l nection 35 from any suitable source of electric energy and a switch 36 is .pivotall connected to the binding post and is a apted when closed to engage with the binding post 33 for closing a clrcuit, a connection 37 leading from the binding post 33 to the

stationary contacts

5 and 6. :As has been pre viously stated one end of each of the coils of the electromagnets are grounded on the plate 15 'of the rotor and thisA ound passes through the shaft 17, the bearing 4 and connection 38. A condenser is shown at 39 and is connectedto the

binding posts

33 and 34 by the

connections

40 and 41 respectively.

-The condenser is shunted acrossthemain circuit and thus eliminates sparking at all of the contacts.

From the above detail description it will be seen that I have provided a magnetic motor in which both permanent and electromagnets are employed the polarity of the electromagnets being changed from N. to S. pole or from S. pole to N. pole, upon operation of the rotor, so that they will be of apolarity opposite to that of the attracting permanent magnet so that the rotor will be continually operated. In other words ashas been described the permanent magnets are so arranged that those of N. pole alternate with those of S. pole and with the switch closed the current flows from the wire 35 through the wire connection 37 to the

contacts

5 and 6 carried by the. base and this the contacts 22 are in engagement with the contacts 5 the left hand coils of the electromagnet will be energized and said magnets will be of S. pole. Upon further movement of ,the rotorthecontacts 22 will be disengaged from the contacts 5 and the contacts 23 will engagethe contactsl therebyy changing the clarity of the electromagnets and making t em N. pole. As an electromagnet of N. pole reaches the centerof or is in alignment with a permanent magnet of S. pole then the polarity of the electromagnet will be changed to S. pole and thereby attracted by the next or adjacent permanent magnet vwhich is of opposite polarity or N. pole. It will thus be seen that the rotor will continue to rotate as there will-be a perv changed upon rotation of the rotor. I have also provided novel means of supporting the rotor relative to the stationary iield or battery ofpermanent magnets and for securing the 'electromagnets to the plates forming a part of the rotor. The ring secured to the underside ofthe base 1 is more particuf rawings. Fig. 4 showing quite clearly how the wire 37 leads to the ring. The ring is at -all times charged so long as the switch member 36 is closed. All of the

contacts

5 and 6 are connected to the ring and therefore each of the contacts is constantly charged so long as the switch 36 is closed.

Having fully described my invention what I claim as new anddesire to secure by Letters Patent is:
